Adding elements to the end of the ArrayList in C#
To add elements to the end of the ArrayList, the code is as follows −
Example
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
ArrayList list = new ArrayList();
list.Add("Andy");
list.Add("Gary");
list.Add("Katie");
list.Add("Amy");
Console.WriteLine("Elements in ArrayList...");
foreach (string res in list) {
Console.WriteLine(res);
}
string[] strArr = { "John", "Jacob" };
list.AddRange(strArr);
Console.WriteLine("Elements in ArrayList...UPDATED");
foreach(String str in list) {
Console.WriteLine(str);
}
}
}Output
This will produce the following output −
Elements in ArrayList... Andy Gary Katie Amy Elements in ArrayList...UPDATED Andy Gary Katie Amy John Jacob
Example
Let us see another example −
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
ArrayList list = new ArrayList();
list.Add("Andy");
list.Add("Gary");
list.Add("Katie");
list.Add("Amy");
Console.WriteLine("Elements in ArrayList...");
foreach (string res in list) {
Console.WriteLine(res);
}
string[] strArr = { "John", "Jacob" };
list.AddRange(strArr);
Console.WriteLine("Elements in ArrayList...UPDATED");
foreach(String str in list) {
Console.WriteLine(str);
}
string[] strArr2 = { "Tim", "Tom", "David" };
list.AddRange(strArr2);
Console.WriteLine("Elements in ArrayList...UPDATED");
foreach(String str in list) {
Console.WriteLine(str);
}
}
}Output
This will produce the following output −
Elements in ArrayList... Andy Gary Katie Amy Elements in ArrayList...UPDATED Andy Gary Katie Amy John Jacob Elements in ArrayList...UPDATED Andy Gary Katie Amy John Jacob Tim Tom David
